2016 Chevy Volt powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.

More 2017 Chevy Bolt powertrain details revealed

We've seen the production version of the Chevy Bolt electric vehicle. We've driven a prototype version. And now it's time to get some details about the powertrain. After the production version's reveal at CES last week, GM trotted out the Bolt EV for its Detroit debut this morning. The company brought with it a bunch of technical specifications. We'll start with the most important part of an EV: the battery. GM has put a 60-kWh lithium-ion battery that weighs just just 960 pounds into the floor of the Bolt. As previously announced, the Bolt's 288 cells will be able to go over 200 miles on a full charge. That full charge takes nine hours on a Level 2 EVSE thanks to the onboard 7.2-kW charger. Of course, a full charge won't be that important most days, which is why GM says that you can get 50 miles of range in "less than two hours" on Level 2. There's a SAE Combo DC fast charging option as well. The battery will have an eight-year/100,000-mile warranty. The Bolt will be able to sprint up to 60 miles per hour in "less than seven seconds" thanks to a 150-kW/200 horsepower motor in the Bolt. The motor is a new GM design that can produce up to 266 pound-feet of torque. The Bolt uses a shift-by-wire system and an, "offset gear and shaft configuration tailored to meet efficiency and performance targets." The Bolt EV's powertrain has a 7.05:1 final drive ratio. You can read all of the details direct from GM below.

It also raises the bar when it comes to driving performance. Engineers developed the Bolt EV's propulsion system to offer more than an estimated 200 miles (based on GM estimates) and a delightful driving experience that's more akin to a compact sports sedan than a small utilitarian crossover. "Being the leader in range and affordability means nothing if the car isn't going to excite you each time you get behind the wheel," said Josh Tavel, Chevrolet Bolt EV chief engineer. "That's why the team was tasked with delivering a propulsion system that would also make the Bolt EV an electric vehicle that owners would love to drive." Single Motor Drive Unit Like most EVs on the road, the Bolt EV's drive system uses a single high capacity electric motor to propel the car.

Corvette Z06 and Viper TA square off at the strip

There are many long-standing grudge matches among automobiles: 911 vs GT-R, Mustang vs Camaro, Ferrari vs Lamborghini... but as far as high-end American metal goes, it doesn't get much more legendary than Viper vs 'Vette. So after Chevy released the new Corvette Z06, we knew it was only a matter of time before it would have to square off against the Viper TA. And what better place to pit these two parallel pillars of American performance than on the drag strip? Fortunately that's just what we have here. In one corner, the 2014 Dodge Viper TA, with its 8.4-liter V10 pumping out 640 horsepower and 600 pound-feet of torque. In the other, the 2015 Chevrolet Corvette Z06, the supercharger on its 6.2-liter V8 more than making up for the discrepancy in displacement and cylinder count to produce 650 hp and just as much torque. But numbers don't tell the whole story, so watch the video clip to see which reaches the end of the quarter-mile first.
